In this online document, we describe the analyses and results of visual models and behavioural assays in the paper “Insect visual sensitivity in the far-red enhances contrast against vegetation”. We provide the code for users to run the analyses step-by-step, and produce the figures from the manuscript.
This document is divided into four parts:
Main models : Shows the main visual models in the paper. Additionally, we combined the models using twilight illumination here for comparison.
Opsin-shifted visual systems : Ran the same models as in the main models, but used opsin-shifted LWS receptors instead of filter-shifted ones.
Evenly space : Test for the effect of evenly spaced photoreceptors on chromatic contrast.
Sensitivity analysis: Test if the modelling results are sensitive to photoreceptor ratio.
Behavioural assay: Details about the behavioural assay which we tested if the living jewel beetles could respond to long wavelength light.
